In Mitch Winehouse’s new memoir, Amy, My Daughter, due out June 28, he writes: “It occurred to me recently that one of the biggest-selling UK albums of the 21st century so far is all about the biggest low-life that God ever put breath into.”

On the show, Winehouse stood by his previous comment explaining that Fielder-Civil led to his little girl’s downfall.

“He introduced her to Class A drugs and she took to it like a duck to water,” he told the host.

Though he does not blame Fielder-Civil for his daughter’s death, Winehouse does think he should take responsibility for her downfall.

“Whether she would have found her way to Class A drugs without him, who knows?” he said. “He ruined something beautiful—his words not mine…He stood up and said it was him, so, that’s who we point the finger at.”

Fielder-Civil is currently serving out a 32-month jail sentence for burglary and other offenses. He has not contacted Mitch since Amy’s death last July.

In his book, Winehouse writes about the other man in Amy’s life: Mark Ronson. The producer took the singer’s love of ’60s girl groups like the Shangri-Las to make the retro-inspired, Back to Black.

Mitch writes that her hit song “Rehab” started as just a conversation the two were having while walking the New York City streets. Amy mentioned, “You know, they tried to make me go to rehab, and I told them no, no, no.” Ronson then responded, “That’s quite gimmicky. We should turn that into a song.”

The two went back to the studio and Amy wrote the song in three hours.
